Samsung Interview Questions, Placement Process, Experience

Samsung Interview Process

I applied for the position of Senior Software Engineer for C++ profile in Samsung through an employee referral. The process took two weeks and then I was interviewed at Samsung. There are three rounds - One written exam and two face to face interviews.

Round 1 - Written Exam
The written test comprised of basic C++ related questions or problems. If your experience is less than three years, then you must appear in the test. The questions are not difficult if your base is strong.

Round 2 - Face to Face Interview
This round includes your resume too. Other than some basic questions related to C++ and threading, you will be asked about your current job profile. Also they will ask you "Why do you want to leave your current company?" So you must be prepared with a good enough reason. Don't sound like you are kind of a guy who joins and leave companies for your self-interest.
Q1. Count the number of bits of an integer.

Round 3 - Face to Face Interview
"Define yourself." This was the first thing that I was asked in this round. But that was just to loosen up the environment. Then some questions regarding programming and data structures were asked. Some questions based on algorithms were asked too.
1) Sort an array which comprises of only 0s and 1s in most efficient way.
2) Given the output when we print in C, C++ and Java, will the answers be different in each case? Why or why not?

After the offer letter was given to me I was called by HR and was asked to visit the Samsung office for an online test. I was worried at first but let me tell you that it regarding some internal process and each of their employees has to go through it. So there is no reason to be worried.

How to crack Samsung Interview

I applied for the senior position and thus I will speak for that only. I have no idea through which process the freshers have to go through.

The written test is simple and since you are experienced, you can vouch for clearing it. There is simple C++ logics that you have to apply while giving the test which should not be a problem.

The first face to face round was tougher for me than the second. The reason is that I am strong with the technical stuff and my concepts are clear, but the questions were regarding my resume and myself. Like I said previously as well, prepare with best possible answers that are realistic enough. Why do you want to join them? Why do you want to leave your current company? What did you learn in your career so far? What projects have you worked on? What problems did you face in those projects? Where do you see yourself in future? What are your dreams? Questions like that, you must prepare.

The second face to face round was more of technical stuff and I enjoyed it. The questions were not too difficult. Prepare for algorithms and data structures well and you will not find a problem.

The Interview at Samsung is easy in comparison to various other companies. I did not find any need for negotiation as the offer made was quite good. The interviewers are nice and very resourceful.

My wishes for all the aspiring candidates.

Tricky Logic Question

A claustrophobic person boards a train that is just about to enter a tunnel.

It is best if the person sits on the back of the train. After the stop, the train will be accelerating as it goes into the tunnel. Thus the train will be much master when the back of the train enters the tunnel. In this way, he will have to spend much less time in the tunnel.

A couple had to take shelter in a hotel for they could not proceed their journey in the rain. Having nothing to do at all, they started playing cards. Suddenly there was a short circuit and the lights went off. The husband inverted the position of 15 cards in the deck (52 cards normal deck) and shuffled the deck.

Now he asked his wife to divide the deck into two different piles which may not be equal but both of them should have equal number of cards facing up. There was no source of light in the room and the wife was unable to see the cards.

For a certain amount of time, she thought and then divided the cards in two piles. To the husband’s astonishment, both of the piles had equal number of cards facing up.

The answer is very simple. All she had to do is take the fifteen cards from the top and reverse them. This would make another pile out of that and there will be two piles - one of 15 cards and one of 37 cards. Also both of them will have the same number of inverted cards.

Just think about it and if the mathematical explanation will help you understand better, here it is.
Assume that there were p inverted cards initially in the top 15 cards. Then the remaining 37 cards will hold 15-p inverted cards.
Now when she reverses the 15 cards on the top, the number of inverted cards will become 15-p and thus the number of inverted cards in both of the piles will become same.

In a recreational activity, you are given four different jars of 2 liters, 4 liters, 6 liters and 8 liters respectively with an unlimited water supply. Then you are asked to measure exactly 5 liters of water using them.

In a jar, there are some orange candies and some strawberry candies. You pick up two candies at a time randomly. If the two candies are of same flavor, you throw them away and put a strawberry candy inside. If they are of opposite flavors, you throw them away and put an orange candy inside.

In such manner, you will be reducing the candies in the jar one at a time and will eventually be left with only one candy in the jar.

If you are told about the respective number of orange and strawberry candies at the outset, will it be feasible for you to predict the flavor of the final remaining candy ?

At each draw, the number of strawberry candies are either decreasing by 2 or not decreasing at all. In the case of orange candies, at each draw, they are either increasing by 1 or decreasing by 1.

Thus on an assumed outset with at least one candy in the jar to begin with, if the number of strawberry candies are 0 or are even in numbers, they will finish off leaving an orange candy at the end. If otherwise, the remaining candy will be a strawberry one.

A strange tradition is followed in an orthodox and undeveloped village. The chief of the village collects taxes from all the males of the village yearly. But it is the method of taking taxes that is interesting.

The taxes paid in the form of grains and every male should pay equal pounds corresponding to his age. In simpler terms, a man aged 10 years will have to pay 10 pounds of grains and a 20 years old will be paying 20 pounds of grain.

The chief stands on a riser containing 7 different weights next to a large 2 pan scale. As per the interesting custom, the chief can only weigh using three of the seven weights.

In such a scenario, can you calculate what must be the weights of the seven weights each and who is the oldest man the chief can measure using those weights?

There are two glasses in front of you. One of the glasses is full of coke and the other glass is full of lemonade. You take a spoonful of coke and mix it into the glass of lemonade. Now the lemonade glass has a mixture of coke and lemonade. You take a spoonful of that mixture and mix it inside the coke glass.

Now what do you think? - The glass with coke has more quantity of lemonade or the glass with lemonade have more quantity of coke mixed with it?

This problem can be solved with algebra as well as logical reasoning. We are going to tell you how it is logically possible.

Be it any quantity that was present in the beginning and any liquid as well. We know that we have taken a spoonful from one glass and put it into another. Then, we have taken a spoonful from the other glass and put it into the first glass. So, at the end of it, the quantity of liquid in either glass remains same as it was in the beginning.

Therefore, we can conclude the fact that any amount of coke that is missing in the glass with coke will be present in the lemonade glass. Also, the same quantity of lemonade will be missing from the lemonade glass and will be present in the coke glass.
